Description

Technical Field

[0001] The present invention belongs to the technical field of foam molding, and particularly relates to a foam furnace device with a shaping function. Background Art

[0002] In the process of foam molding or in foam polymer materials, a honeycomb or porous structure is formed through the addition and reaction of physical or chemical blowing agents. The basic steps of foam molding are the formation of bubble nuclei, the growth or expansion of bubble nuclei, and the stabilization of bubble nuclei. Under given temperature and pressure conditions, the solubility of the gas decreases until it reaches a saturated state, causing the excess gas to be expelled and form bubbles, thereby achieving nucleation.

[0003] For example, the SAN foam board is a lightweight porous material based on styrene-acrylonitrile copolymer (SAN) and is made through a foaming process; the SAN foam board is mostly made through a compression molding foaming process. During compression molding foaming, a special mold restricts the shape of the foam molding, making the formed SAN foam board regular and without burrs after foaming.

[0004] However, after molding, the foam board is in a tight state against the inner wall of the mold. During demolding, the friction between the foam board and the mold is large, and it is easy to cause damage to the outer peripheral surface of the foam board. Summary of the Invention

Detailed implementation manners

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Please refer to Figures 1 to 8 , a foaming furnace device with a shaping function of the present invention will be described. A foaming furnace device with a shaping function includes a body 10 having a forming cavity 101, a mold 20, an adjusting member, a plugging unit 30 and a lifting unit 40; the mold 20 is arranged in the forming cavity 101, an annular expansion cavity 201 is formed in the mold 20, and an extrusion material is filled in the expansion cavity 201; the adjusting member is communicated with the expansion cavity 201 and is used to fill the expansion cavity 201 with the extrusion material or empty the expansion cavity 201; the plugging unit 30 includes a machine cover 301 above the forming cavity 101 and a cover plate 302 arranged on the bottom wall of the machine cover 301, the machine cover 301 is used to seal the forming cavity 101, and the cover plate 302 is used to seal the opening of the mold 20; the lifting unit 40 is connected to the machine cover 301 and is used to drive the machine cover 301 to move in the up and down direction.

[0020] Optionally, the extrudate is water, and the regulating member is a water pump and an air pump. Water injection and pumping into the expansion cavity 201 are completed by the water pump, and the regulating member is connected to a water tank and an air tank.

[0021] Before forming, the gas in the air tank is pumped into the expansion cavity 201 by the air pump so that the air pressure in the expansion cavity 201 returns to the atmospheric pressure, and then the water in the water tank is pumped into the expansion cavity 201 by the water pump; when demolding, the water in the expansion cavity 201 is first pumped out by the water pump, and then the expansion cavity 201 is pumped to a negative pressure state by the air pump.

[0022] Optionally, the extrudate is a thermally stable polymer (such as silicone-based gel), and the regulating member is a pressure pump, and the regulating member is connected to a storage tank.

[0023] Before foam molding, the regulating member pumps the extrudate from the storage tank into the expansion cavity 201, and when demolding, the regulating member pumps the extrudate from the expansion cavity 201 into the storage tank.

[0024] Compared with the prior art, in the foam furnace device with a shaping function provided in this embodiment, the annular expansion cavity 201 inside the mold 20 is arranged around the forming area, and its cross-sectional shape matches the contour of the target foam part. When the foaming material is injected into the mold 20, the regulating member injects the extrudate into the expansion cavity 201 to completely fill the expansion cavity 201. During the heating stage, when the foaming material expands due to heat, the extrudate in the expansion cavity 201 exerts a uniform radial restraint force on the forming area, forcing the inner wall of the mold 20 to fit tightly with the foaming material; after the foam shaping is completed, the regulating member switches to the negative pressure mode to withdraw the extrudate, so that the volume of the expansion cavity 201 is emptied, thereby forming a demolding gap between the mold 20 and the formed part, reducing the large friction force between the formed part and the mold 20, and reducing the damage to the outer peripheral surface of the formed part.

[0025] In some embodiments, refer to Figure 2 and Figure 4 , a plurality of clamping units 50 are provided in the forming cavity 101. The plurality of clamping units 50 are arranged at intervals along the edge of the forming cavity 101. An annular sliding cavity 102 is formed in the inner wall of the forming cavity 101, and an annular guide rail 103 is fixedly provided on the inner wall of the annular sliding cavity 102.

[0026] The clamping unit 50 includes a moving seat 501 and a positioning member. The moving seat 501 is provided with a sliding groove 5011 that is slidably adapted to the annular guide rail 103. A pressing member 60 is provided in the sliding groove 5011, and the pressing member 60 expands and contracts in the vertical direction; the positioning member is provided on the moving seat 501, and the positioning member expands and contracts in a direction away from or close to the outer wall of the mold 20.

[0027] It should be noted that a connecting cavity 5012 for accommodating the pressing member 60 is formed in the inner wall of the sliding groove 5011.

[0028] The moving seat 501 is matched with the guide rail through the sliding groove 5011 to realize the circumferential position adjustment on the inner wall of the forming cavity 101. After determining the position of the moving seat 501, the pressing member 60 extends out so that the moving seat 501 is fixed to the annular guide rail 103. By adjusting the position of the moving seat 501, the pressing position of the positioning member against the outer wall of the mold 20 after extension is the optimal stress point, improving the stability of the mold 20 during the foaming molding process; and the position of the positioning member can be adjusted arbitrarily, and it can also adapt to molds 20 of different shapes, improving the application range of the device.

[0029] In some embodiments, the pressing member 60 is a telescopic oil cylinder, a hydraulic cylinder, or an electric cylinder.

[0030] In some embodiments, referring to Figure 4 , the pressing member 60 includes a first telescopic device 601 and a pressing seat 602; the first telescopic device 601 telescopically moves in the up and down direction, and the fixed end of the first telescopic device 601 is fixedly connected to the inner wall of the sliding groove 5011; the pressing seat 602 is fixedly connected to the movable end of the first telescopic device 601.

[0031] Specifically, the first telescopic device 601 is a telescopic oil cylinder, a hydraulic cylinder, or an electric cylinder.

[0032] When the first telescopic device 601 extends out, it drives the pressing seat 602 to move towards the annular guide rail 103, thereby fixing the relative position of the moving seat 501 and the annular guide rail 103 through friction; it should be noted that the pressing seat 602 has a concave surface matching the annular guide rail 103, and the concave surface increases the contact area with the annular guide rail 103, thereby improving the static stability of the moving seat 501.

[0033] In some embodiments, referring to Figure 4 , a receiving cavity 6021 is formed on one side of the pressing seat 602 facing the annular sliding rail. A first telescopic member 6022 is arranged in the receiving cavity 6021. The first telescopic member 6022 telescopically moves in the up and down direction. The fixed end of the first telescopic member 6022 is fixedly connected to the inner wall of the receiving cavity 6021. A lifting plate 6023 is fixedly connected to the movable end of the first telescopic member 6022. A universal wheel 6024 is installed on the side of the lifting plate 6023 facing away from the first telescopic member 6022, and the universal wheel 6024 abuts against the annular guide rail 103.

[0034] Specifically, the first telescopic member 6022 is a telescopic oil cylinder, a hydraulic cylinder, or an electric cylinder.

[0035] The first telescopic member 6022 is extended to drive the lifting plate 6023 to move toward the direction close to the annular guide rail 103, so that the universal wheel 6024 contacts the annular guide rail 103, and when the movable seat 501 slides, the universal wheel 6024 rolls to reduce friction, thereby extending the service life of the annular guide rail 103; the first telescopic member 6022 is retracted to drive the lifting plate 6023 to move away from the reversing guide rail, so that the universal wheel is separated from the annular guide rail 103, and then the clamping member 60 moves toward the direction close to the annular guide rail 103 until the clamping member 60 is clamped against the annular guide rail 103.

[0036] In some embodiments, see Figure 5 The positioning member includes a second telescopic device 502 and a limiting rod 503 ; the second telescopic device 502 is extended and retracted in a direction close to or away from the mold 20 , and the fixed end of the second telescopic device 502 is fixedly connected to the movable seat 501 ; the limiting rod 503 is connected to the movable end of the second telescopic device 502 .

[0037] Specifically, the second telescopic member 303 is a telescopic oil cylinder, a hydraulic cylinder, or an electric cylinder.

[0038] The second telescopic device 502 pushes the limiting rod 503 to abut against the outer wall of the mold 20, fixes the mold 20 through radial pressure, and radially clamps to prevent the mold 20 from moving, thereby ensuring the position of the mold 20; the telescopic structure is suitable for molds 20 of different specifications and molds 20 of different shapes, thereby improving the applicability of the device.

[0039] In some embodiments, see Figure 5 and Figure 6 The clamping unit 50 also includes a mounting seat 504, a swivel 505, a driving member 506 and an angle adjustment assembly; the mounting seat 504 is fixedly connected to the movable end of the second telescopic device 502, the limit rod 503 is hinged to the mounting seat 504, and the hinge axis of the limit rod 503 is parallel to the up and down direction; the swivel 505 is rotatably connected to the mounting seat 504; the driving member 506 is transmission-connected to the swivel 505, and is used to drive the swivel 505 to rotate with the telescopic direction of the second telescopic device 502 as the rotation axis; the angle adjustment assembly is connected to the swivel 505, and is used to adjust the angle between the limit rod 503 and the mounting seat 504.

[0040] Specifically, the driving member 506 is a motor, the output shaft of the driving member 506 is fixedly connected with a driving gear 5061 , and the outer peripheral surface of the rotating ring 505 is provided with teeth meshing with the driving gear 5061 .

[0041] Specifically, a mounting block 5031 is hinged at the end of the limiting rod 503 , and the mounting block 5031 is screwed to the mounting seat 504 .

[0042] The driving member 506 starts to drive the driving gear 5061 to rotate. The driving gear 5061 drives the driven gear to rotate, and the driven gear drives the rotating ring 505 to rotate. During the rotation of the rotating ring 505, the limiting rod 503 is driven to rotate around the hinge axis through the angle adjustment assembly, thereby adjusting the angle between the limiting rod 503 and the mounting seat 504, and thus adjusting the clamping angle to adapt to the contour of the mold 20, improving the clamping stability of the mold 20.

[0043] The limiting rod 503 is set to be detachably connected, and the limiting rod 503 with different lengths can be replaced to abut against the outer wall of the mold 20, so as to be applicable to molds 20 with more shapes; the second telescopic member 502 can adjust the protruding length of the limiting rod 503 in a small range. When the telescopic length of the second telescopic member 502 cannot meet the requirement, the limiting rod 503 can be replaced to adapt to the length reaching the outer wall of the mold 20.

[0044] In some embodiments, referring to Figure 5 and Figure 6 , the rotating ring 505 is provided with two through holes 5051 arranged oppositely. There are two angle adjustment assemblies, and the two angle adjustment assemblies are relatively arranged on both sides of the rotating ring 505.

[0045] The angle adjustment assembly includes a transverse movement rod 507, an elastic rod, a pressing block 509 and a pressed block 510; the transverse movement rod 507 is slidably connected to the inner wall of the through hole 5051, and the transverse movement rod 507 slides radially along the rotating ring 505; the elastic member 508 is fixedly connected between the transverse movement rod 507 and the mounting seat 504, and has a pre-tightening force that makes the transverse movement member away from the limiting rod 503; the pressing block 509 is fixedly connected to the inner wall of the through hole 5051; the pressed block 510 is fixedly connected to the outer wall of the transverse movement rod 507, and the pressed block 510 is provided with an inclined surface that abuts against the pressing block 509.

[0046] Specifically, a substrate 5041 is provided on one side of each of the two transverse movement rods 507 facing away from each other. The substrate 5041 is fixedly connected to the mounting seat 504, and the elastic member 508 is fixedly connected between the substrate 5041 and the transverse movement rod 507. The elastic member 508 is a spring, and the elastic member 508 is sleeved on the outer periphery of the transverse movement rod 507.

[0047] It should be noted that when one of the pressing blocks 509 presses against the corresponding pressed block 510, the other pressing block 509 moves away from the corresponding pressed block 510.

[0048] When the rotating ring 505 rotates, one of the pressing blocks 509 pushes the pressed block 510 through the inclined surface, overcomes the resistance of the elastic member 508 to make the transverse movement rod 507 move radially to press the limiting rod 503. At this time, the other pressing block 509 moves away from the pressed block 510, and the elastic member 508 releases the elastic force to make the transverse movement rod 507 move radially away from the limiting rod 503, thereby changing the angle between the limiting rod 503 and the mounting seat 504.

[0049] In some embodiments, see Figure 2 The outer wall of the mold 20 is provided with a limiting hole 202 which is plugged and matched with the limiting rod 503.

[0050] The limiting rod 503 is inserted into the limiting hole 202 on the outer wall of the mold 20 to form a plug-in hard constraint, thereby completely limiting the position of the mold 20 and further improving the clamping stability of the mold 20 .

[0051] In some embodiments, see Figure 7 The blocking unit 30 further includes a second telescopic member 303 disposed between the machine cover 301 and the cover plate 302 , and the second telescopic member 303 is telescopic in the up-down direction.

[0052] The second telescopic member 303 independently controls the distance between the cover plate 302 and the machine cover 301, ensuring that the cover plate 302 always presses the opening of the mold 20, thereby adapting to molds 20 of different thicknesses and improving the application range of the device.

[0053] In some embodiments, see Figure 8 There are two lifting units 40, which are relatively arranged on both sides of the machine cover 301. The lifting units 40 include a screw 401 and a power piece 402; the axial direction of the screw 401 is parallel to the up and down direction, the screw 401 is rotatably connected to the machine body 10, and the screw 401 is also screwed to the machine cover 301; the power piece 402 is transmission-connected to the screw 401, and is used to drive the screw 401 to rotate with the up and down direction as the rotation axis.

[0054] Specifically, the power component 402 is a motor.

[0055] The power part 402 drives the screws 401 on both sides to rotate synchronously, driving the cover 301 to rise and fall smoothly along the thread pair. The double screw 401 structure eliminates the risk of overloading in single-point drive and ensures the horizontal movement of the cover 301; the self-locking feature of the thread drive prevents accidental sliding, which is highly safe.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
